project.assets.json contains invalid targets

### Description

The `project.assets.json` generated from the maui template contains a target for an Android app running on an iOS simulator: `net8.0-android34.0/iossimulator-arm64`. Other nonsensical targets include `net8.0-ios17.2/android-arm` and `net8.0-maccatalyst17.2/android-x86`.

I noticed this behavior while trying to debug the following error in a production project (don’t know whether it’s related):
> Assets file '[project]/obj/project.assets.json' doesn't have a target for 'net8.0-maccatalyst/maccatalyst-arm64'. Ensure that restore has run and that you have included 'net8.0-maccatalyst' in the TargetFrameworks for your project. You may also need to include 'maccatalyst-arm64' in your project's RuntimeIdentifiers.

### Steps to Reproduce
